Abstract
A solar cell element is disclosed. The solar cell element comprises a semiconductor substrate and electrodes. The semiconductor substrate with a first and second main surface comprises a body and a first layer. The electrodes comprise first electrodes on the first layer and second electrodes on the second main surface. At least one of the first electrodes and the second electrodes comprises silver, copper and nickel as a main component. A method for manufacturing a solar cell element is disclosed. An electrically conductive paste containing silver, copper and nickel is prepared. The electrically conductive paste is applied on the semiconductor substrate. The electrically conductive paste is fired to form the solar cell element.
